It is not good enough for checking efficacy of gypsy moth treatment blocks.

For years 1990 - 1991, 1:100,000 USGS quadrangles were used. In years, 1992 and 1993, defoliation was transferred from sketch maps or 1:50,000 aerial photos to 1:50,000 mylars of roads and streams created with a GIS. In year 1994, the data was created from sketch maps by the Virginia Department of Forestry.
